Open camelCase, snake_case and kebab Converter →Case conversion splits into two jobs. Writers need UPPERCASE, lowercase and Title Case to fix a heading or rescue a sentence typed with caps lock on. Developers need to move identifiers between camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE when crossing language or API naming conventions. Many converter pages only do the first job, or wrap it in so many ads the retype would have been faster.
The case converter covers the writing cases plus the common code cases instantly as you paste. For programming work specifically, the code case converter transforms identifiers between camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case, which takes the tedium out of renaming across a codebase boundary.
